What a butterface gets done in order for men to find her attractive. These women feel that big boobs will negate their ugly faces when the better choice would have been to get the plastic surgery done on said butterface.

When you insert your cock inside the crevece formed by two breasts, preferably large ones, and the owner of the breasts takes the two breasts and moves them up and down your cock until you splooge all over her face.

Act of doing plastic surgery on breasts in order to make them become bigger or (rarely) smaller.
A lot used in the show-business world, this trend is conveyed by TV shows such as Nip/Tuck or Grey's Anatomy.
It is of course something very common in porn/erotic models to have enhanced breasts.

This girl has nice breasts...
No she got a boobjob recently, i don't like te fake ones !

when one, preferably male,( unless you take it the other way) swivelchair's (yes that is a verb) his tongue around the nipple, arousing it to full potential...occasionally mistaking it for a lollypop, this male should begin to devour the aereola until orgasm occurs. or until girl pretends to orgasm because male is an incompetent drool bag..
